FAQ

Q1: What is the operating principle of the 3300 XL 8 mm probe?

A1: It operates on eddy current technology, detecting changes in magnetic fields to measure the distance between the probe tip and the shaft surface.

Q2: What type of surfaces can the probe measure accurately?

A2: It is optimized for conductive metallic surfaces, typically steel shafts, but may require calibration for other materials.

Q3: Can the probe be used with non-Bently Nevada proximitor modules?

A3: For best performance, it should be paired with Bently Nevada 3300 XL Proximitor sensors. Using non-matching components may cause accuracy issues.

Q4: What is the probe’s frequency response capability?

A4: It supports measurement frequencies up to 10 kHz, suitable for most rotating machinery applications.

Q5: How does the probe maintain calibration over long distances?

A5: It uses matched cable assemblies and Proximitor sensors to ensure system calibration integrity, even at extended lengths.

Q6: Does temperature affect measurement accuracy?

A6: While extreme temperatures may affect material properties, the probe is designed to maintain accuracy across -35 °C to +177 °C.

Q7: Is the probe resistant to electrical noise in industrial environments?

A7: Yes, the coaxial cable design and robust shielding minimize interference from electromagnetic noise.

Q8: How is shaft vibration amplitude calculated from probe signals?

A8: The proximitor converts probe signals into a voltage proportional to shaft displacement, which is then analyzed by the monitoring system.

Q9: Can multiple probes be installed on a single machine?

A9: Yes, typically two probes are installed orthogonally to measure both X and Y axis vibrations, and additional probes may monitor axial displacement.

Q10: How does this probe compare to the 5 mm series?

A10: The 8 mm series provides a wider linear range and is better suited for larger shaft diameters, while the 5 mm series is used in confined installation spaces.
